a. 313.171081 miles/hour

b. 0.434m

To calculate the speed in miles per hour, you need to change meterinto miles (1m = 0.086992mile), then second into hour (1s = 1/3600h). The calculation would be:

140 m/s x 0.086992mile/m : 1/3600 s/hour = 313.171081 miles/hour.

To calculate the next question you need to know that mili second = 1/1000 second. Then the calculation would be:

140m/s x 3.1ms x 1/1000 = 0.434m
