Question

Antelope runs top speeds at 97 km/h, suppose it runs 1.5 km with an average speed of 85km/h, and then runs 0.80 km with an average speed of 67 km/h. How long will it take the antelope to run 2.3 km

Answer 1

Answer:

107 seconds

Explanation:

$Time=\frac {Distance}{Speed}$

Time taken to travel 1.5 Km at a speed of 85 km/h=$\frac {1.5}{85}=0.017647059 hours$

Time taken to travel 0.8 Km at a speed of 67 km/h = $\frac {0.8}{67}=0.011940299 hours$

Total distance= 1.5+0.8=2.3 km

Total time=0.017647059+0.011940299=0.029587357  hours

Converting hours to seconds, we multiply hours by 3600 hence total time=0.029587357*3600=106.5144864  seconds,

Rounding off, time=107 seconds
