Multiply 125.5 miles by 1.61 to get total kilometers:

125.5 x 1.61 = 202.055 kilometers total.


Divide 150 minutes by 60 to get total hours:

150/ 60 = 2.5 hours.

Now Divide total kilometers by total hours to get kilometers per hour:

202.055 kilometers / 2.5 hours = 80.822 kilometers per hour.

Round the answer as needed.

Answer:

80.822 km/hour

Step-by-step explanation:

A train travels in 150 minutes = 125.5 miles.

First we will convert 125.5 miles to kilometers

1 mile = 1.61 kilometers

125.5 miles = 125.5 × 1.61

                   = 202.055 kilometers

1 hour = 60 minutes

150 minutes = \frac{150}{60}

                    = 2.5 hours

Hence the train travels 202.055 kilometers in 2.5 hours.

Therefore, The speed of the train in one hour = \frac{202.055}{2.5}

                                                                           = 80.822 km/hour

The trains speed is 80.822 km/hour.

o-na [289]

Given:

Jada traveled 135 miles in 3 hours.

Andre traveled 228 miles in 6 hours. Both Jada and Andre traveled at a constant speed.

To find:

How far did Jada travel in 1 hour?

Solution:

We have,

Distance traveled by Jada in 3 hours = 135 miles

Then,

Distance traveled by Jada in 1 hour = \dfrac{135}{3} miles

                                                           = 45 miles

Therefore, Jada travel 45 miles in 1 hour.

1. Jada measured the height of a plant in a science experiment and finds that, to the nearest 1/8 of an inch, it
Nonamiya [84]

Answer:

here

Step-by-step explanation:

Given that the height(h) of the plant to the nearest 1/4 of an inch is 3/4 inches = 0.75 inches.

it is obvious that the height will lie within the range

Thus,

a. The largest actual height could be 0.875 inches, while

b. The smallest actual height could be 0.625 inches

c. The percentage error is given by the formula

if we take the lowest value, for instance, as the exact, i.e. 0.625 inches, then % error = [(0.75-0.625)/0.75]*100% = 16.7%
