Question

Two cars A and B race each other. The Car A ran for 2 minute at a speed of 7.5 km/h, slept for 56 minute and again ran for 2 minute at a speed of 7.5 km/h. find the average speed of the car A in the race.​

Answer 1

Answer:

We know that

Distance=speed×timeDistance=speed×time

Distance travelled in first 2 minute = 7.5×2607.5×260 = 0.25 km

Distance travelled in last 2 minute = 7.5×2607.5×260= 0.25 km

Total distance = .25+.25 = 0.5 km

Total time = 2+2+56 = 60 minute = 1 hr

Average speed = 0.5/1

= 0.5 km/hr

We know that

Distance=speed×timeDistance=speed×time

Distance travelled in first 2 minute = 7.5×2607.5×260 = 0.25 km

Distance travelled in last 2 minute = 7.5×2607.5×260= 0.25 km

Total distance = .25+.25 = 0.5 km

Total time = 2+2+56 = 60 minute = 1 hr

Average speed = 0.5/1

= 0.5 km/hr
