Step-by-step explanation:
1.Let the common multiples be X
2.so 3x+4x=140
3.so 7x=140
4.so x=140/7
5.so X=20
6.so Time spent in running =3×20=60 hours
7. so Time spent in Cycling =4×20=80 hours
8. Proof=60+80=140 hours

Step-by-step explanation:
Ratio =3:4
total hours = 140
total ratio = 3+4 = 7
no. of hours he cycled = 4× ̶̶1̶̶4̶̶0 = 20 = 4×20
̶7̶
= 4 ×20 = 80
no. of hours he runs = 20 × 3 = 60
total hours = 80 + 60 = 140
