Question

Josiah can jog 5/6 mile in 15 min find his average speed in miles per hour

Answer 1

10/3 miles per hour

Explanation:

Given that,

→ 5/6 mile in 15 min

→ 15 min × 4 = 1 hour

Average speed in miles per hour,

→ 5/6 × 4

→ 20/6

→ 10/3 miles per hour

Hence, required answer is 10/3.

Answer 2

• 3 1/3 miles per hour

Explanation:

Given speed:

• 5/6 mile per 15 min

Convert this to mph as follows:

• 5/6 mile per 15*1/60 h, since 1 min = 1/60 h
• 5/6 mile per 1/4 h, simplify
• 5/6 : 1/4 mile per 1/4 : 1/4 h, divide both sides by 1/4
• 5/6 *4 mile per 1 h, multiply
• 10/3 mile per hour,
• 3 1/3 miles per hour, convert to mixed fraction
