Question

In the first race ramesh gives suresh a head start of 150 meters and still wins the race by 30 seconds. in the second race, ramesh gives suresh a head start of 250 meters and still wins the race by 10 seconds. find the speed (in meter/min) of suresh.

Answer 1

The speed of suresh = distance/time
= s1+s2/t1+t2
= 150+250/30+10
= 400/40
=10 m/s
= 10×60m/min
= 600 m/min
Hence, the speed of suresh is 600 m/min


Hope this helps !

Answer 2

Answer:

300

Step-by-step explanation:

For Suresh, 150 meter head start means a final loss by 30 seconds and 250 meters head start means a final loss by 10 seconds. This means that he covers 100 meters in 20 seconds. Therefore, he covers 5 meters in 1 second i.e. 300 m/min. Hence, 300

5 meter in 1 sec.

5*60-----1*60 (convert sec in min)

300
