Hi! For such questions i think it’s easier if you convert the units first. For example 1km/h = 1000m/3600s. For question (b), try converting 1m/s to km/h first before multiplying in the 36. Do give it a try for the other questions!

You can try to convert all the values to the correct units you want them to be in. Then simplify the ratio between the denomenator and the numerator
