Answer: 210 km

Step-by-step explanation:

To find the answer, you need to translate the time given into all hours. 20 minutes is 1/3 of an hour so we have 2 and 1/3 hours total. Then all you need to do is multiply that number, 2 and 1/3 hours, by the 90 km/h. You get 210 km total as your answer.

Answer:

210km

Step-by-step explanation:

20min=60/3=⅓ hours.

So the car runs for:

2h+1/3h=(6+1)/3=7/3hours

Distance=speed×time=90m/h×7/3h=210km

Fill the missing values to make the equations true.

Logarithm properties:

$\displaystyle \log_a b+\log_a c=\log_a (b\cdot c)\\\\\log_ab-\log_a c=\log_a \left( \frac{b}{c} \right)\\\\\log_{a^p}b^q= \frac{q}{p} \log_a b$

According to this, we can get:

$\displaystyle a)\log_7 3+\log_7 8=\log_7 (3\cdot 8)=\log_724\\\\b) \log_89-\log_85=\log_8 \frac{9}{5}\\\\c)\log_325=2\log_35$
