 Mentor P: 7,318 Surely you have some idea as to how to do this. Am I correct in reading the first to be converting MegaJoules to Joules. You should be able to figure that out with a bit of thought. Lets go through the conversion of $\frac {km} h$ to $\frac m s$ There are 1000 m per km and 3600 s per h so $$\frac {km} h \times \frac {1000m} {1km} \times \frac {1h} {3600s}$$ examine the units in this expression, note that km appears in both the numerator and denominator, so can be canceled, leaving only m. The same is true for h. Do the arithmetic.
