How many miles did Brian bike?
Recall;
Speed = distance ÷ time
Distance = speed × time
Speed = 12.2 mi/hr
biking time = 1.45 hours
Distance (mountain biking) = 12.2 × 1.45 = 17.69 miles
Answer:
87.648
Step-by-step explanation:
It may be hard to multiply decimals. However, if you can break the decimal up into two separate equations, it can make it easier. Solving 73.04 x 1.2 is the same as solving (73.04 x 1) + (73.04 x 0.2). You already can say that 73.04 x 1 is 73.04. And then you can solve 73.04 x 0.2. Solving 73.04 x 0.2 is the same as solving 73.04 divided by 5, which will get you 14.608. Finally, all you have to do is add the two sums (73.04 + 14.608) which will get you your answer of 87.648.
