Question

puneet goes for jogging everyday for 45 minutes find. a. his speed if he covers a distance of 7.5 km b. the distance covered jobs at the speed of 12 km/h​

Answer 1

Solution: When time is fixed speed and distance are in direct variation.

[ •°• Distance(km) 7.5 | s ]

[ •°• Speed (km/h) s | 12]

Thus, time = Distance_1/Speed_1

= Discount_2/Speed_2

=> 3/4 = 7.5/s = d/12

Thus, 3/4 = 7.5/s => 4×7.5/3 = 30/3 = 10

And, 3/4 = d/12 => d = 9

Thus, a. Punnet jobs for 7.5 km at the speed of

10 km/h, and b. Punnet jobs for 9 km at the speed of 12 km/h
