A train moves at a constant speed of 75km / hour i.) How far will it travel in 20 minutes? ii.) Find the time required to cover a distance of 250km
Answers
Answer:
250km in 3hr 20 min
Step-by-step explanation:
Given: Speed of train = 75kmph
To Find: Distance Travelled in 20 minutes, Time required to cover 250km.
Formulation: Speed of the train is 75kmph, i.e, it requires 1 hour (60 minutes) for the train to cover 75km.
Formula:
(i) Substituting x1 = 60 y1 = 75 and x2 = 20 in the formula,
Gives y2 = 25 km
∴The train will move 25km in 20 minutes
(ii) Substituting x1 = 60 y1 = 75 and y2 = 250 in the formula,
Gives x2 = 200 minutes or 3 hours 20 minutes
∴The time required to cover a distance of 250km is 3 hours 20 minutes.
Answer:
Train cover 25 km in 20 minutes
Train cover 250km in 3 hours and 20 minutes
Step-by-step explanation:
sol 1. 25×20/60 = 25
sol. 2 250/75 = 3 and 25 is raminder i.e. train cover 25km in 20 minutes so the answer is 3 hours and 20 minutes
