Question

1. spirit of australia, a hydroplane boat, made speed records by traveling 225 miles in 45 minutes. what is its record breaking speed in terms of km/min? answer:

Explanation:

Step1: Convert miles to kilometers

1 mile is approximately 1.60934 km. So, 225 miles is $225\times1.60934 = 362.1015$ km.

Step2: Calculate speed

Speed $v=\frac{d}{t}$, where $d$ is distance and $t$ is time. Here, $d = 362.1015$ km and $t = 45$ minutes. So, $v=\frac{362.1015}{45}=8.0467$ km/min.

Answer:

$8.0467$ km/min
