Question

A train travels 125.5 miles in 150 minutes 1 mike = 1.61 kilometers 1 hour = 60 minutes find the trains speed in kilometers per hour

Answer 1

80.822 km/hour

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 =
`(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 =
`(202.055)/(2.5)`

= 80.822 km/hour

The trains speed is 80.822 km/hour.

Answer 2

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.
