Question

Speedometer readings for a motorcycle at 12-second intervals are given in the table.

t (s)	0	12	24	36	48	60
v (ft/s)	32	28	25	21	25	27

(a) Estimate the distance traveled by the motorcycle during this time period using the velocities at the beginning of the time intervals.

___ ft

(b)Give another estimate using the velocities at the end of the time periods.

___ ft

Answer 1

Instructions seem pretty clear. Are you having trouble doing the arithmetic?

For example, the velocity at the beginning of the first time interval is 32 ft/s, so the estimate for the distance traveled during this interval is

(32 ft/s) * (12 s) = 384 ft

For the second time interval the estimate is 28*12 = 336 ft. Just continue the process.
