Question

Saul wants to bike 48 kilometers to taste some really good mangoes.

Answer 1

Answer:

$\textsf{1)} \quad t=\dfrac{48}{r}$

$\textsf{2)} \quad \sf 2.4\:hours=2\:hours\:24\:minutes$

Step-by-step explanation:

Part 1

$\boxed{\sf Time=\dfrac{Distance}{Speed}}$

Given:

• Time = t hours
• Distance = 48 km
• Speed = r km/h

Substitute the given values into the formula:

$\implies t=\dfrac{48}{r}$

Part 2

Substitute r = 20 km/h into the derived equation from part 1 and solve for t:

$\implies t=\dfrac{48}{20}=2.4\: \sf hours$

Note: 2.4 hours = 2 hours 24 minutes

Answer 2

Answer:T=48/r and 2.4 hours
