Question

Sam and Bruno were computing how many kilometers they rode in the 3 bike trips they took last month. In order, they rode 45.7, 40.9, and 38 miles. Their solutions are shown.


Sam’s Solution
Bruno’s Solution
45.7 + 40.9 + 38.0 = 124.6 miles. 124.6 times 0.621 = 77.38 kilometers.
45.7 + 40.9 + 38.0 = 124.6 miles. 124.6 divided by 0.621 = 200.64 kilometers.

If one kilometer equals 0.621 miles, which is the best solution to find the total number of kilometers they rode? Why is it correct?
Bruno is correct. When going from a larger unit to a smaller unit you need to divide.
Bruno is correct. When going from a smaller unit to a larger unit you need to divide.

Sam is correct. When going from a smaller unit to a larger unit you need to multiply.

Answer 1

its b cause sam does 124.6 × 0.621 = 77.38 kilometers. 124.6 × 0.621 = 77.38 kilometers.
bruno did 45.7 + 40.9 + 38.0 = 124.6 miles. 124.6 divided by 0.621 = 200.64 kilometers.
now if u remember 1 kilometer = 0.621 miles.
so therefore bruno is correct When going from a larger unit to a smaller unit you need to divide
