A boat can travel 23mph in still water. If it travels 248 miles with the current in the same length of time it travels 120 miles

mixas84 [53]

Answer: the speed of the current is 8 mph.

Step-by-step explanation:

Let represent the speed of the current

boat can travel 23mph in still water. This means that the total speed with which the boat travelled is (23 + x) mph.

Time = distance/speed

If it travels 248 miles with the current, it means that the time it took the boat to travel with the current is

248/(23 + x)

in the same length of time it travels 120 miles against the current. This means that the total speed with which the boat travelled is (23 - x) mph. The time it took the boat to travel against the current is

120/(23 - x)

Since the time is the same, it means that

248/(23 + x) = 120/(23 - x)

Cross multiplying, it becomes

248(23 - x) = 120(23 + x)

5704 - 248x = 2760 + 120x

120x + 248x = 5704 - 2760

368x = 2944

x = 2944/368

x = 8 mph

Wyatt and his little sister are saving up money to buy a joint birthday present for their mother. Wyatt already has $20 saved an

Ilia_Sergeevich [38]

Answer:

The two siblings will have saved the same amount towards their mother's gift after 3 weeks.

Amount saved by Wyatt = $\$41$

Amount saved by Wyatt's sister = $\$41$

Step-by-step explanation:

Let $t$ (in weeks) denotes the time period by which the two siblings will have saved the same amount towards their mother's gift.

Wyatt already has $20 saved and plans to save $7 per week from his allowance.

Amount saved by Wyatt = $20+7t$

Wyatt's sister has $14 saved so far and will save $9 per week from hers.

Amount saved by Wyatt's sister = $14+9t$

To find the time period by which the two siblings will have saved the same amount towards their mother's gift,

solve the following equation.

$20+7t=14+9t\\20-14=9t-7t\\6=2t\\3=t$

So, the two siblings will have saved the same amount towards their mother's gift after 3 weeks.

Amount saved by Wyatt = $20+7(3)=20+21=\$41$

Amount saved by Wyatt's sister = $14+9(3)=14+27=\$41$
