Answer:

Abelito had the greater average speed

Step-by-step explanation:

Given

Bobby:

Distance =4\ miles

Time = 30\ minutes

Abelito

Distance = 10\ miles

Time = 48\ minutes

Required:

Who had a greater average speed

Average speed (S) is calculated as:

S = \frac{Distance}{Time}

We will make use of mph (miles per hour) as the unit of speed.

For Bobby:

S_B = \frac{4\ miles}{30\ minutes}

Convert minute to hour

S_B = \frac{4\ miles}{0.5\ hr}

S_B = 8mph

For Abelito

S_A = \frac{10\ miles}{48\ minutes}

Convert minute to hour

S_A = \frac{10\ miles}{0.8\ hr}

S_A = 12.5mph

By comparison: 12.5mph > 8mph

Hence: Abelito had the greater average speed
