1.	A loaded truck travels 14 km in 25 minutes. If the speed remains the same, how far can it travel in 5 hours?
Answer» Time and distance are in direct proportion ⇒ \(\frac{x_1}{y_1}= \frac{x_2}{y_2}\) x₁ = 14 km , x₂ = ? y₁ = 25min = 25/60hr = 5/12hr = y₂ = 5hrs ⇒ x₂= (x₁×y₂) / y₁= (14 × 5)/5 = (14 × 5 × 12)/5 = 168 km ∴ Lorry travelled in 5 hrs = 168km

Answer»

Time and distance are in direct proportion

⇒ \(\frac{x_1}{y_1}= \frac{x_2}{y_2}\)

x₁ = 14 km , x₂ = ?

y₁ = 25min = 25/60hr = 5/12hr = y₂ = 5hrs

⇒ x₂= (x₁×y₂) / y₁= (14 × 5)/5 = (14 × 5 × 12)/5

= 168 km

∴ Lorry travelled in 5 hrs = 168km
