Rate of one --- x
rate of the other --- 2x
They both drove for 1 hour, so their distance are 1(x) and 1(2x) km
connect the dots for me.

V1 = X km/h.
V2 = 2x km/h.
d1 = V1 * t = x * 1 = X km.
d2 = V2 * t = 2x * 1 = 2x km.
d2 - d1 = 2x - x = 240.
X = 240 km. = d1.
2x = 2 * 240 = 480 km. = d2.
d1 = V1 * t = 240,
V1 * 1 = 240,
V1 = 240 km/h.
d2 = V2 * t = 480,
V2 * 1 = 480,
V2 = 480 km/h.
Was it 2 buses or 2 planes?
The speed is too high for a bus.
V2 = 2x km/h.
d1 = V1 * t = x * 1 = X km.
d2 = V2 * t = 2x * 1 = 2x km.
d2 - d1 = 2x - x = 240.
X = 240 km. = d1.
2x = 2 * 240 = 480 km. = d2.
d1 = V1 * t = 240,
V1 * 1 = 240,
V1 = 240 km/h.
d2 = V2 * t = 480,
V2 * 1 = 480,
V2 = 480 km/h.

V2 = 2x km/h.
d1 = V1 * t = X * 1 = X km.
d2 = V2 * t = 2x * 1 = 2x km.
d2 - d1 = 2x - (-x) = 240 km.
2x + x = 240,
X = 80 km = d1.
d2 = 2x = 2 * 80 = 160 km.
d1 = V1 * t = 80,
V1 * 1 = 80,
V1 = 80 km/h.
d2 = V2 * t = 160,
V2 * 1 = 160,
V2 = 160 km/h.
V2 = 2x km/h.
d1 = V1 * t = X * 1 = X km.
d2 = V2 * t = 2x * 1 = 2x km.
d2 - d1 = 2x - (-x) = 240 km.
2x + x = 240,
X = 80 km = d1.
d2 = 2x = 2 * 80 = 160 km.
d1 = V1 * t = 80,
V1 * 1 = 80,

d2 = V2 * t = 160,
