Jason drives to his parents' house and back home the same way. On the way to his parents' house, his speed is 10 kilometers per hour slower than his speed on his way back, and therefore it takes him 20 minutes longer. If Jason drives to his parents' house at 50 kilometers per hour, how many minutes does he spend on his way back from his parents' house?
A. 60
B. 80
C. 100
D. 120
E. 150
The OA is C.
I'm confused with this PS question. Experts, any suggestion about how can I solve it?
Can I say that he drives back from his parents' house at 40 kilometers per hour? then
The total time on his way back will be, t+20. I stuck here. Any expert help me, please? Thanks in advance.
