Find speed, distance and time; solve rate problems

Use the speed–distance–time triangle to find any one from the other two — speed = distance ÷ time, distance = speed × time, time = distance ÷ speed — and solve multi-step rate and average-speed problems.

Kavi Races the Sunset 🌇

Kavi flew 120 km in 2 hours to reach the valley before dark. "How fast was I going?" she wonders. "Speed is just distance shared out over time — 120 km in 2 hours is 60 km every hour, so 60 km/h. And it works all three ways: once I know any two of speed, distance and time, I can always find the third ⚡."

What your child will learn

1One triangle, three formulasSpeed tells you how far you travel in one unit of time — 60 km/h means 60 km every hour. Picture a triangle with Distance on top and Speed × Time underneath. Cover the quantity you want, and the triangle shows you the calculation.

2A steady journey is equal hops of speedAt a steady 60 km/h, every hour adds another 60 km. Tap Hop +60 to add one hour and watch the distance grow signpost by signpost.

A peek inside

A coach travels 240 km in 4 hours at a steady pace. What is its speed?

speed = distance ÷ time = 240 ÷ 4

Try this at home: Find the SPEED: a car goes 150 km in 3 h. speed = __
