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 =
= 2.5 hours
Hence the train travels 202.055 kilometers in 2.5 hours.
Therefore, The speed of the train in one hour =
= 80.822 km/hour
The trains speed is 80.822 km/hour.
