Complete the following.
(a) 1.57 105 km/h2 = km/h·s
(b) 1.57 105 km/h2 = m/s2
(c) 37 mi/h = ft/s
(d) 37 mi/h = m/s

I don't understand how to convert these i have tried to convert them and i got them all wrong please help! Thanks

I will do two:

1.57E5km/h^2 (1E3m/km)(hr/3.6E3)^2

37mi/hr*1.6km/mi*1E3m/km*1hr/3600s
