A car travels at constant speed for 7 days and covers 1500 miles. What is the speed in centimeters/minute? You may use the (approximate) conversion factors on page 55 of the text (in particular that 1 mile is about 8/5 km), or you may relate everything to the conversion 1 inch = 2.54cm.

Yosef French · Answer 1

(1500 mi / 7 da) · (1 da / 1440 min) · (1609.3 m / 1 mi) · (100 cm / 1 m)

= (1500 · 1 · 1609.3 · 100) / (7 · 1440 · 1 · 1) cm/min

= 23,948.6 cm/min
