Question

22. I walk a certain distance and ride back taking a total
time of 37 minutes. I could walk both ways in 55
minutes. How long would it take me to ride both
ways?
(a) 19 min
(6) 38 min
(c) 18 min
(d) None of these​

Answer 1

Answer:

(a) 19 min

Step-by-step explanation:

Walk + ride back = 37 minutes.    

Walk + Walk = 55 minutes.

2 * walk = 55 minutes.

Walk = 55/2 = 27.5 minutes.    

Putting equation (2) in equation (1).

27.5 + ride back = 37

Ride back = 37 - 27.5 = 9.5.

2 *ride back = 9.5 *2 = 19 minutes.
