Question

A train runs at a speed of 90km/hr for 2 1/2 hours. What should be its speed if it has to cover the same distance in 2 hours? ​

Answer 1

Answer:

Step-by-step explanation:

s=d/t

90=d×2/5h

d=225

when covering the distance in 2hrs,

s=225÷2

=112.5km/h

Answer 2

Step-by-step explanation:

Speed = distance/ time

90 = distance/2.5

90 × 2.5 = distance

225 km = distance

Speed = distance / time

Speed = 225/2

Speed = 112.5 km/hr
