Answer» Step-by-step explanation: Speed of BUS = D / T = 225 / 3 = 75 KM/h Speed of another bus = 75 + 15 = 90 km/h Total time consumed by second bus to cover 90 km is one hour. So.. time TAKEN by second bus to cover 225km = 225 / 90 × 1 = 2.5 HR

Answer»

Step-by-step explanation:

Speed of BUS = D / T

= 225 / 3 = 75 KM/h

Speed of another bus = 75 + 15 = 90 km/h

Total time consumed by second bus to cover 90 km is one hour.

So.. time TAKEN by second bus to cover 225km

= 225 / 90 × 1

= 2.5 HR
