The total distance travelled by the train is 426 miles
To obtain the answer to the question given above, we shall determine the distance travelled by the train in each case.
Case 1:
Average speed = 80 mph
Time = 4.2 h
Distance 1 =?
Average speed = distance / time
80 = Distance 1 / 4.2
Cross multiply
Distance 1 = 80 × 4.2
Distance 1 = 336 miles
Case 2:
Average speed = 60 mph
Time = 1.5 h
Distance 2 =?
Average speed = distance / time
60 = Distance 2 / 1.5
Cross multiply
Distance 2 = 60 × 1.5
Distance 2 = 90 miles
Finally, we shall determine the total distance travelled by the train.
Distance 1 = 336 mile
Distance 2 = 90 miles
Total distance =?
Total distance = Distance 1 + Distance 2
Total distance = 336 + 90
Total distance = 426 miles
Therefore, the total distance travelled by the train is 426 miles
